static charge

[ICY_SNAKE]

Hello,

mostly when i touch the screen during printing, the duet runs in the routine to change the filament.

I think there is somehow static charge.

Has someone information about it?

Also if i resume after filament change it will not start at the last point. Always with an offset.

Any guess??

Thx
Dieter

@icy_snake by "the screen" do you mean PanelDue, or a 12864 display, or something else?

@icy_snake is there a button on your PanelDue page to run that change filament routine? If so then the static discharge is probably being interpreted by the touch screen as touching that button.

@dc42 yes thats what i think is happen.

I will try after the print is ready some grounding to the printer an the display box.

I will inform you about my results.
